Colony morphology of 208F/Stk cells is unaffected by Hyal2 expression. 208F/Stk c12 and c13 cells were transduced with retrovirus vectors expressing the indicated proteins or were not transduced (None), the cells were seeded at low density, and colony morphologies were evaluated 1 week after seeding. In the right panel, the numbers of flat (bottom black bar) and refractile (top black bar) colonies were counted separately. In the left panel these categories were combined. The experiment was repeated with similar results.
